Compact wideband circularly polarized antenna and its self-decoupled MIMO configuration for 28-GHz band targeting 5G/6G millimeter-wave networks
A compact circularly polarized antenna optimized for broadband operation around the 28-GHz band is proposed, utilizing a ring-shaped radiator excited through a via-fed central patch which enables strong impedance matching and stable circular polarization.
